摘要
计及流固耦合影响，本文提出了包括波浪载荷、模态分析和船体薄壁梁结构的波浪载荷响应的理论计算方法．用本文方法和相应计算程序计算了一条６ｍ 长钢质船模的固有频率、振型及弯扭耦合波激振动响应．模态分析结果同常规有限元计算作了比较．计算中还讨论了一些波浪参数的变化对波激振动响应的影响．
Taking account of the coupling of the fluid and solid, the paper provides a theoretical method of wave loads, mode analysis and wave induced vibration response of ship hull with thin walled beam. Using the method, we made a calculation on a steel ship model chosen for the numerical example. The calculation result of the mode analysis is compared with the result using the finite element method. Some influence on dynamic responses has been discussed in the example.
